An elevation of privilege vulnerability exists when the Windows User Profile Service (ProfSvc) improperly handles symlinks, aka 'Windows User Profile Service Elevation of Privilege Vulnerability'.

Microsoft Windows Server 2008 R2 and R2 SP1 and Windows 7 Gold and SP1 do not properly enforce AppLocker rules, which allows local users to bypass intended access restrictions via a (1) macro or (2) scripting feature in an application, as demonstrated by Microsoft Office applications and the SANDBOX_INERT and LOAD_IGNORE_CODE_AUTHZ_LEVEL flags.

An elevation of privilege vulnerability exists in Windows store installer where WindowsApps directory is vulnerable to symbolic link attack, aka 'Microsoft Windows Store Installer Elevation of Privilege Vulnerability'.

An elevation of privilege vulnerability exists when the Windows User Profile Service (ProfSvc) improperly handles symlinks. An attacker who successfully exploited this vulnerability could delete files and folders in an elevated context. To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and delete files or folders of their choosing. The security update addresses the vulnerability by correcting how the Windows User Profile Service handles symlinks.

The Duo Authentication Proxy installer prior to 5.2.1 did not properly validate file installation paths. This allows an attacker with local user privileges to coerce the installer to write to arbitrary privileged directories. If successful, an attacker can manipulate files used by Duo Authentication Proxy installer, cause Denial of Service (DoS) by deleting file(s), or replace system files to potentially achieve elevation of privileges. This is only exploitable during new installations, while the installer is running, and is not exploitable once installation has finished. Versions 5.2.1 of Duo Authentication Proxy installer addresses this issue.

NVIDIA GeForce Experience, all versions prior to 3.22, contains a vulnerability in GameStream plugins where log files are created using NT/System level permissions, which may lead to code execution, denial of service, or local privilege escalation. The attacker does not have control over the consequence of a modification nor would they be able to leak information as a direct result of the overwrite.
